Twitter Teams Up with Foursquare for Location Tagging

Earlier today, Twitter announced that Foursquare will soon power location tagging across the company's suite of apps. In a video shared today, Twitter showed how location data by Foursquare will be embedded into Twitter for iPhone to allow users to tag specific places instead of using Twitter's previous (coordinate-based) location database.

This is an interesting move for a couple of reasons. First off, Twitter has chosen to rely on a third-party for a precise database of places instead of building its own from scratch – and they cleverly picked Foursquare, which has amassed an impressive collection of 65 million places in six years. I'm curious to see if Twitter will use this newfound power to enhance ads and offers on the service (imagine Foursquare-powered deals available in a Twitter card).

Second, Twitter needs to improve their local discovery features. With a richer collection of places, Twitter could unlock previously unseen contextual, local features that wouldn't be possible with simple coordinates (think venues like concerts and museums or spots like a cafe in Rome).

In addition to building the world’s most accurate place database, we’ve learned how to see buildings the way our phones see them — as shapes and sensor readings on the ground rather than boxes viewed from space. We’ve built software that can understand when people move through, stop within, and then move on from these shapes — whether the shapes are places, neighborhoods or cities. And we’ve built search and recommendation algorithms that get smarter as they learn about the shapes you choose to spend time in and the shapes you simply pass through. You’ll hear us talk about these things as “stop detection,” “snap-to-place,” “the Pilgrim engine” — they’re the pieces that make us confident that no matter where you’re standing in the world — whether it’s your own neighborhood or a far-away city you’re visiting for the first time — we can raise your awareness of the best experiences nearby and help you find places you’ll love.
